RESUMEN

The flood disaster in the region of the Oder and Elbe Rivers or the disaster in Eschede, Kaprun, or Ramstein make us aware that disasters not only occur in distant regions of the world but also in our latitudes. They do not follow any rules; no one can predict the location, time, or type of a disaster. However, this lack of concrete predictability should not lead to our being unprepared to respond to catastrophic events. Detailed examination and analysis of medical and organizational activities involved in past disasters reveal that these types of incidents always entail similar medical and logistic consequences. Dealing with disasters necessitates cooperation between numerous organizations and people. This requires clearly structured facilities for information, communication, and decision making as well as a well-defined process flow. In addition to basic planning and practicing of these processes for medical management of catastrophes-such as searching for and rescuing victims, triage, performing life-saving emergency procedures, definitive medical treatment, and transfer of patients-establishing structures for disaster preparedness is indispensable to meet the demands of mass cases of ill or wounded individuals.

RESUMEN

Every year many disasters cause thousands of injuries, deaths, refugees. Earthquakes and war often cause severe injuries (burns; amputations; Crush-Syndrome; gunshots; landmines; nuclear, biological or chemical warfare / hazardous material; infectious diseases; pediatric specialties). Referring to big earthquakes in the last few years up to 20.000 thousand people were killed (India 2001). 310.000 deaths were caused by war in 2001. The Mass Casualty Incident is characterized by the disbalance between victims and the normal community emergency response. Because of this a lot of different institutions and organizations are involved in coping with the disaster. This produces an extensive demand of qualified Command, Control and Communication (C3). Furthermore a lot of data has to be collected during the treatment and the injuries need special medical treatment. The use of health telematics in disaster response helps to cope with the scenario. Modern technologies provide support for building up medical aid although the normal infrastructure is destroyed. To cope with disaster scenarios there are some telematic tools which can be used: computer based Command and Control System, telemedical support, and data-resources-network/Medical Intelligence. The International Center for Telemedicine at the University of Regensburg Medical Center provides support for Health Care Professionals as a competence center for telemedicine. For the eastern part of Bavaria it develops a telemedical network with many components: The mobile emergency care system NOAH (Notfall-Organisations- und Arbeits-Hilfe) supports the Emergency Medical Service. Local Health Networks and the Clinical Network of Eastern Bavaria connect physicians and hospitals with the Regensburg Medical Center. With an online-education tool participants from all over the country can take part in trainings and courses.

RESUMEN

We report on the successful treatment of a seriously traumatized patient (injury severity score=59) who presented with exsanguinating hemorrhage in the emergency room. Preclinical and emergency room management included "small volume" hypertonic resuscitation as well as massive transfusion, C-clamp stabilization of a pelvic ring instability, and attachment of external fixators to multiple bone fractures. During the intensive care period,we started enteral immunonutrition immediately after an abdominal compartment syndrome was removed by laparotomy and a jejunal catheter had been inserted. Multiple fractures were stabilized rapidly and the soft tissue wounds were covered by split skin grafts. Additionally, we provided sufficient analgesia with few side effects using an epidural catheter for continuous application of local anesthetics. In summary, an effective synthesis of up-to-date strategies for preclinical, emergency room, and intensive care management prevented multiple organ failure and achieved survival with good quality of life after a "fatal" multiple trauma.

RESUMEN

Experiencing communication problems in our emergency services, we developed an innovative communication network and system the NOAH-system (NOAH, which stands for Notfall -, Organisations - und Arbeitshilfe or Emergency-Organisation Active Aide System). In contrast with the currently established emergency services communication in Germany by radio wave, data is transferred from the scene in the form of an electronic record on a mobile computer by means of the wireless data communication network Modacom (Mobile Data Communication), which is provided by German Telekom. It is received at the dispatch-centre in mentioned format and transferred to the admitting hospital without any loss of data. - In a prospective study, the technical and conceptual suitability of this system was investigated. It was shown that an admitting hospital was informed more than 20 minutes in advance about the admittance of a patient. To assure the quality of transferred data, information was ranked by different criteria. This further demonstrated that much more precise information about a patient's condition was already available upon admittance in the hospital.

RESUMEN

We have developed a communication system in which data are transferred from the scene of an emergency in the form of an electronic record on a notepad computer by means of a satellite link (MODACOM). The data are received at the dispatch centre and transferred to the admitting hospital automatically. In a prospective study of 53 emergencies the technical suitability of the system was investigated. First-sight information could be fed into the computer in 15 s and transmitted within 3 min of arrival on the scene. For 16 patients with life-threatening conditions, the admitting hospital was notified on average after 13.6 min (SD 6.0), whereas by conventional VHF radio it took 35.5 min (SD 8.9). In addition, more precise information about the patient's condition was received at the hospital.

RESUMEN

The growing complexity of the performance processes in medicine makes it mandatory that the flow of information is faster and more consistent, especially when the sites of health care are far away from each other. The Regensburg model, a realization of lean telemedicine from a low-cost domain, using PC-based standard videoconferencing systems shows the use of modern telecommunications, especially in trauma surgery. In 203 prospectively evaluated teleconsultations between 15 participants a total of 697 images were transmitted via videoconferencing. In 95% of the trauma cases the transmitted material was judged as at least sufficient. In project-attending evaluations the efficacy of these systems and their use were clearly demonstrated. Savings in transportation costs of up to 4,400 DM per case were achieved. Through quicker flow of information quality improvements for all participants resulted; to some extent considerable costs for health care were avoided or reduced. Based on these thoughts, a new platform of communication will be established in Regensburg as a closed medical intranet for the region of eastern Bavaria.

RESUMEN

Growing complexity of performance processes in medicine require a quicker and more consistent flow of information, even between distant sites of health care. The Regensburg model, a realisation of lean telemedicine from a low-cost domain, using PC-based standard videoconferencing--systems shows the use of modern telecommunications especially in medical spheres. In project-related evaluations, the efficacy of these systems as well as their use can clearly be proven. Through a quicker flow of information, quality improvements for all participants resulted, and to some extent considerable costs for health care were avoided or lowered.
